Abstract (en)
[origin: GB2518660A] The loudspeaker includes a conical diaphragm 20 having a central aperture with a collar 28 upstanding from the perimeter of the central aperture 26 of the diaphragm, a spider 30 having a central aperture 36, the spider having a collar 38 upstanding from the perimeter of the central aperture of the spider, and a voice coil former 40. The collar of each of the cone and the spider are concentrically located around an end region of the voice coil former to form an elongate neck region 12. The use of the elongate neck region allows for the cone, spider and voice coil former to be joined more easily therefore forming a more reliable and durable join. Preferably the join is a soldered join.
